Performance Procedures

Testing the Monitor  

This test checks the performance of ECG synchronization between the monitor and a 
defibrillator. The ECG sync performance test is required once every year and when the 
monitor is repaired or when the monitor’s parts are replaced.

•

Dynatech Nevada MedSim 300 or equivalent simulator

•

Defib Sync Cable (M4820A) or Switchcraft 850

•

Switchcraft 750 

Two sections are needed to complete the connection from the monitor to the simulator.

1. If a Defib Sync Cable is available, connect it the ECG Sync output on the monitor, then 

to the Switchcraft 750. 
or 
If a Switchcraft 850 is available, connect it the ECG Sync output on the monitor, then 
to the Switchcraft 750.

2. Connect the Switchcraft 750 to the SYNC/A PACE input on the simulator

"cardioversion: converted" (this message will persist on the simulator)

If the monitor isn’t working properly, messages such as the following may 
appear: "cardioversion: vfib", "cardioversion: late".
